Buick LaCrosse

Buick LaCrosse

The Buick LaCrosse is a mid-size car produced by the Buick division of American automaker General Motors since 2004 as the 2005 model year. The LaCrosse, only available as a four-door sedan, replaces the Buick Century,Buick Regal and the Oldsmobile intrigue after gm discontinued the brand. Its namesake is the Buick LaCrosse concept car shown beginning in 2000.

The original name was inspired by a Buick concept car of the same name shown in 2000 and also used as a reference to the sport of lacrosse, seen as popular with a younger, more active demographic to which Buick sought to market. However, la crosse means masturbation or swindling in Québecois slang, so it is sold as the Buick Allure in Canada.

First generation (2005-2009)

The LaCrosse made its debut in late 2004 as a 2005 model with the intention of replacing the Century and Regal midsize cars with a single model. Riding on a revised version of the W-body known as MS2000, the LaCrosse was initially available with two powerplant choices in three trim levels: a 3.8 L 3800 Series III V6 available in base CX and mid-level CXL forms, and a 3.6 L HFV6 V6 in the top line CXS model. Power is routed to the front wheels via a 4T65-E automatic transmission (4T65-E HD on Super's).

For 2008 the LaCrosse was facelifted, with the most noticeable change being that of replacing the old oval grille with a chrome u-shaped waterfall style grille. 2008 model year also introduced the LaCrosse Super, featuring a smallblock V8 engine, which replaces the previously top-of-the-line CXS model.


A new trim of the LaCrosse bearing the Super moniker debuted at the 2007 New York International Auto Show, to be introduced as a 2008 model. The LaCrosse Super is positioned as a higher-performance model of the sedan with revised front end styling influenced by the 2004 Velite concept car, as well as 4 portholes (reflecting a V8 engine under the hood), a rear spoiler, projector beam fog lights, Magnasteer, larger brakes, and revised suspension tuning with standard Stabilitrak. Interior changes include special super badged cluster with blue face, wood grain shift knob, and dream weave leather seating. Interior colors for the super come only in Platinum or Mocha Brown, while exterior color choices are Mocha Brown Metallic, Black Onyx, Red Jewel Tincoat, and Platinum Metallic. Power comes from the LS4 5.3 L small-block V8 engine featuring Active Fuel Management technology. This powertrain is also found on the Grand Prix GXP, Impala SS, and Monte Carlo SS. The Super model is the fastest modern production Buick ever built, with a factory top speed of , and 0-60 mph times of 5.7 seconds. Only the grand nationals of the 1980's were faster.
